AbstractThe Ni-Al-NO3 layered double hydroxide (LDH) compound has been intercalated with benzoate anion through an anion exchange process for amoxicillin drug adsorption. The purpose of this research is to synthesize Ni-Al-NO3, ion exchange with benzoate anion to form Ni-Al-Benzoate, and then applying it as an adsorbent of amoxicillin. The adsorption process was carried out using the batch technique. The materials synthesized in this study were characterized by Fourier Transform Infrared Spectroscopy (FT-IR), X-ray ray diffraction (XRD), and Thermogravimetric Analysis/Differential Thermal Analysis (TGA/DTA). The exchange of benzoate in Ni-Al-Benzoate LDH by amoxicillin was followed by UV-Vis spectrophotometry. The pH, LDH amount, and contact time are optimized. The adsorption of amoxicillin by Ni-Al-Benzoate is fit to the pseudo-second-order kinetics model, with an adsorption capacity of 40 mg/ g. The results showed that anion exchange was successfully carried out between benzoate anion and amoxicillin.
